Bulk-Absorption Charging Voltage
2 Concord 8D (258 AH each) Freedom 25 Inverter-Charger (130 amp) Trimetric 2025 Gauge I'm dry camping and charging my batteries. They were 30% discharged. My Concords call for 14.2-14.4v absorpti...

Battery voltage rising with constant amps is good. (bulk stage) Keep it going and see if the voltage settles at the set Vabs.
I don't know your equipment but the amps are well below 130a at 47a. Is that deliberate by some setting you did? Some of those have reduced 120v amps you can choose that affects the DC amps output.
Otherwise it seems your batteries are higher in SOC than you thought, so only accepting lower amps or they are at much less capacity than you think, (sulfation?) so they have a lower acceptance rate at 70% SOC and 14v than you would think.
